Drag selection coordinates in iMagine Photo

Hi all,

I’m trying to make a small application that opens a pdf file. Then the user must drag a selection and then the pdf is cropped to the selection.
I’m using iMagine Photo and UI browser and so far the PDF opens fine and is displayed the way I want, I can’t find any info on how to monitor dragging :frowning:

Does anyone know how I can get the start and end coordinates of the drag session?

I guess ones I have them I gan get iMagine Photo to crop it etc…

Thanks

BTW I’m using OS 10.4.2
